    A 75 kg man running at 2.5 m/s jumps off a roof that is 3 m high. As he hits the ground, he tucks into a ball and rolls without slipping to break his fall. Modeling the man as a solid sphere of a radius 0.75 m, assuming no rotational motion before he hits the ground, and ignoring any effects of him tucking into a ball, what is his center of mass velocity on the ground?

    A 40.0-kg child running at 3.00 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.50 m from the axis of rotation of the merry-go-round. The child is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 600 kg ? m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after the child has jumped onto it?...
